Hey folks, proud to present LYNX Tools, a collection of production proven open source tools to accelerate your workflows!
All mentioned tools are free to download via the links below and are licensed with a full HoudiniFX license. All Houdini Assets have complete Houdini native documentation available.
Repository: https://github.com/LucaScheller/VFX-LYNX
Lastest stable release: https://github.com/LucaScheller/VFX-LYNX/releases
Please give them a test drive, so we can improve them further
Roadmap | https://trello.com/b/f8Pgip7s/lynxpipeline
So far there are three tools:
LYNX_force_general | Tweak your sims with this all purpose & intuitive force field. Built to mimic force fields in other DCC applications, but with support for more features and a natural Houdini user experience.

LYNX_fabric | Create fabric/weave patterns with ease. Perfect for creating that holiday sweater you never wanted.
https://www.lucascheller.de/vfx/2019/03/16/vfx-lynx-houdini-fabric-asset/
LYNX_velocity | Get control of your velocities via an intuitive UI or groom them for absolute fine tuned control.

Hello everyone!
This is the first demo of a new tool I've been working on in Houdini. The idea is to simplify the process of adding steel reinforcement in concrete fractures, specifically FRC (fiber reinforced concrete)
My aim is to produce a single node that takes your simmed geometry and adds these steel fibers along the fractured surfaces. Here are some examples of my tool so far:
password = vfx
Current controls:
- max fiber length
- randomize fiber length
- max angle (before fiber breaks from the adjacent piece)
Things I plan to add:
- randomize max angle
- fragments of concrete stuck to fibers (as seen in example video below)
- fiber straightness (how straight/crooked the fibers are)
If you have any cool ideas or suggestions, or feedback on my work so far, let me know!
(The idea was inspired by the following breakdown video at 2:39)

Hi
I have to work on and animated piece of cloth where the individual square pieces are docking into the animation.
How would you go about the rendering? I got an attribute that separates bright pieces from the dark ones. Can call that attribute into the shader but need more variation. Would you use a for each loop to iterate over each piece in order to apply e.g. individual uvs for each piece? The material should be very sparkly on some parts.

Hello all,
I was wondering if anyone has any experience working with Infiniband and Houdini. I have recently purchased two Voltaire HCA700ex2-q Infiniband cards (40Gb/ps) and have them connected via a Mellanox 40Gb capable fiber qsfp+ cable. I've already upgraded the firmware on both cards to the newest available version. And both cards can see each other and I am able to set up and transfer files between them using shared drives in Windows 7 Professional x64. (I will be trying this next in CentOS 7) What my question is: how do I get the two computers to see each other in Hqueue so that I can use my faster Infiniband connection rather than my much slower gigabit Ethernet connection which is getting fully saturated during distributed fluid sims. Do I need to edit the client information in some way to use the IP from the Infiniband card (cards are capable of 10Gb/ps IPoIB)?
Thanks,
Ryan
